Skinpass Rolling of Thin Steel Strip KIJIMA Hideo*1 Abstract: Skinpass rolling (or temper rolling) is usually the final process in the production of coldrolled steel sheets. One of the main objectives in skinpass rolling is to obtain a certain surface roughness profile. In this paper, the mechanism of roughness profile transfer in skinpass
Home >Steel Forming Process: Hot Rolled, Cold Rolled, Forging Casting, Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steel's recrystallization temperature When steel material is above the recrystallization temperature, it can be shaped.
More information . In case of stainless steel, the process is more complex, with previous stages passing through a previous heat treatment of the coils, in bell furnaces, after the hot rolling process, reaching cold rolling mills with input thicknesses between and mm to be later cold rolled with target thicknesses between and 6 mm. The cold rolling mill responsible for the ...
The data contained in this article was acquired from the automatic gauge control system for a steel cold rolling mill production line in Nigeria. Accuracy is the one of the most important indices of productivity during a milling process. A total of 486 data points were obtained from selected feedbac .
In terms of usage, hot rolling processes more tonnage than any other manufacturing process, and cold rolling processes the most tonnage out of all cold working processes. Roll stands, holding pairs of rolls, are grouped together into rolling mills that can quickly process metal, typically steel, into products such as structural steel (Ibeams, angle stock, channel stock, and so on), bar stock ...
